Other (non-earthquake) This is a very interesting account of a seiche in Lake Chelan following the Yakutat Bay, Alaska earthquake (Magnitude 8.6, September 10; 11:40 Alaska Standard Time). It was transcribed from the Chelan Leader in the WPPSS documents: "A Volcanic Upheaval -- The Leader is informed that about 2 o'clock p.m. last Sunday, up the lake about 19 miles at E. F. Christie's place, J. A. Graham saw out near the center of the lake a peculiar upheaval of the glassy surface to the height, apparently, of about 6 or 10 feet. He afterwards watched the waves roll in towards shore. The water came in like a tidal wave, all of slx feet high, driving the little steamer Kitten, moored there, high upon the rocks, then receding, caused it to upset and sink. Succeeding waves continued for two hours before the lake finally quieted down. All observers agree that there was no wind blowing at the time. At Mountain Park, four miles this side, T. R. Gibson says the wave from the upheaval was only 20 minutes in reaching there. The steamer Dexter, which came down Tuesday and assisted in raising the Kitten, reports that the wave was very noticeable at Moore's Point and the head. Judge I. A. Navarre, who came down from 10 miles up 25-mile creek on Tuesday, is said to have been told by some prospectors up there that the creek--one of the largest tributaries of the lake--went dry for about three hours on Sunday afternoon, and then resumed its natural flow..."

A Volcanic Upheaval The Leader is informed that about 2 o'clock p.m. last Sunday, up the lake about 19 miles at E. F. Christie's place, J. A. Graham saw out near the center of the lake a peculiar, upheaval of the gassy surface to the height, apparently, of about 6 or 10 feet. He afterwards watched the waves roll in towards shore. The water came in like a tidal wave, all of slx feet high, driving the little steamer Kitten, moored there, high upon the rocks, then receding, caused it to upset and sink. Succeeding waves continued for two hours before the lake finally quieted down. All observers agree that there was no wind blowing at the time. At Mountain Park, four miles this side, T. R. Gibson says the wave from the upheaval was only 20 minutes in reaching there. The steamer Dexter, which came down Tuesday and assisted in raising the Kitten, reports that the wave was very noticeable at Moore's Point and the head. Judge I. A. Navarre, who came down from 10 miles up 25-mile creek on Tuesday, is said to have been told by some prospectors up there that the creek--one of the largest tributaries of the lake--went dry for aboul three hours on Sunday afternoon, and then resumed its natural flow, which, if true, would indicate a disturbance of some nature--probably volcanic--in the moun- tains. It was certainly a strange and unusual occurrence, and only for the credibility of our informants, we should be inclined to think it a great big sell. Chilliwack Progress August 19, 1915 Chilliwack, B. C. Chilliwack Valley Experiences Shake ------------------------- Late Sleepers Rudely Awakened by a General Shaking Up of Surroundings - No Damage. ----------------------------- Chilliwack city and valley experienced a real shake yesterday morning a few minutes after six o'clock, which lasted several seconds. The tremor was the most pronounced experienced since 1871, and was sufficient to arouse late sleepers, by the shaking of houses and rattling of windows. Whether the shake was caused by a real earthquake or the fall of a massive glacier in the mountains caused by a long season of dry weather is a matter of conjecture. The latter view is accepted by many from that the disturbance appears to have been con- fined to the valley, including the Agassiz district. In 1871 it was discovered after the shock of that time, that a big slice of Mount Cheam peak had dropped about one thousand feet.

Transcription: The September 10, 1899, Alaska earthquake (magnitude 8.6) caused an avalanche at a distance of 690 kilometers (430 miles) from the epicenter (Morton and Streitz, 1967). This earthquake also caused a seiche in Lake Chelan with waves of up to 6 ft. to 10 ft. and which continued for two hours (Chelan Leader, September 14, 1899).
